This is a set of medium tension D'Addario Prelude standard scale 3/4 size double bass strings.

Prelude bass strings are multi-stranded steel core strings that produce a warm tone quality with good bow response. The special core design and reduced tension creates strings that are very easy to play, especially for younger, developing players. Ideal for use in educational environments, Prelude bass strings maintain a clear, warm sound that blends well across the ensemble.
